Broken beer bottle but Amstel don't care!

I bought two six packs of Amstel Radler. It turns out one of the bottles had the entire end sheared off leaving a very sharp and jagged edge. It could very easily have caused a very nasty cut. I emailed the 'customer care' e-mail address with photographs - 5 days later no response. I messaged them on fb messenger - no response. So much for 'customer care' Amstel!!!!
